[PATCH v7 0/2] Add initial support for Qualcomm Kuno SoC

[Hardeep Sharma <hardeep.sharma@oss.qualcomm.com>]

This series adds initial support for the Qualcomm Kuno SoC and the Kuno
IDP reference board.

Kuno is a 32-bit ARM (Cortex-A7) Qualcomm platform. The rest of the
series (bindings, GCC, RPMh clocks and power domains, interconnect,
pinctrl, geni-se) has been applied and is in linux-next, so v7 carries
only the SoC and IDP board devicetree, plus a small geni-se binding
update that lets the QUP wrapper use one address/size cell on 32-bit
SoCs.

Changes in v7:
- Addressed v6 review feedback:
  - New patch: allow 1 or 2 #address-cells/#size-cells in the geni-se
    QUP wrapper binding.
  - Switched the QUP wrapper to one address/size cell with an empty
    ranges, instead of the explicit 32-bit window.
- Link to v6: https://lore.kernel.org/all/20260929-kuno-soc-support-v6-1-a16afafbcbc7@oss.qualcomm.com/

Changes in v6:
- Rebased on next-20260928. The rest of the series has been applied,
  so only the devicetree patch remains.
- Addressed v5 review feedback:
  - Added the full qcom,pdc-ranges map (22 ranges instead of 3), so
    that all PDC-routed wakeup GPIOs can wake the system.
  - Added wakeup-parent = <&pdc> to the TLMM node.
  - Replaced the explicit soc ranges with an empty ranges and named the
    node soc, matching the other 32-bit Qualcomm SoCs.
  - Widened the QUP wrapper ranges to cover the whole 32-bit address
    space instead of a 16 MiB window.

Changes in v5:
- Selected QCOM_GDSC from the Kuno GCC config. The driver registers GDSCs
  (added in v4), so like the other Qualcomm GCC drivers it must select
  QCOM_GDSC; otherwise, in a configuration where nothing else enables it
  (e.g. COMPILE_TEST or a minimal Kuno-only build), gdsc_register() returns
  -ENOSYS and the clock controller fails to probe.
- Link to v4: https://lore.kernel.org/all/20260827-kuno-soc-support-v4-0-dd34f235fc1a@oss.qualcomm.com/

Changes in v4:
- Addressed v3 review feedback:
  - Registered the interconnect NoC provider from an explicit
    core_initcall() instead of module_platform_driver(), matching the
    established qcom interconnect driver convention.
  - Replaced the NA mux-slot placeholder with _ across the pinctrl
    PINGROUP table, matching the upstream qcom pinctrl convention.
  - Added minItems: 1 to the interconnect binding clocks property so a
    single clock is valid (system-noc), and aligned the binding
    examples with the sdx75 labelled-node style.
  - Added GDSC power-domain support to the Kuno GCC: the binding now
    defines GDSC macros and the driver registers the EMAC0, PCIe and
    USB20 GDSCs, so #power-domain-cells has real backing providers.
  - Split the cpu-idle-states phandle list so each phandle is on its
    own line.
  - Collected Acked-by / Reviewed-by tags from v3.
- Link to v3: https://lore.kernel.org/all/20260821-kuno-soc-support-v3-0-196e2b306368@oss.qualcomm.com/

Changes in v3:
- Addressed v2 review feedback:
  - Reworked the interconnect binding clocks: dropped clock-names and
    replaced the flexible min/maxItems list with fixed per-compatible
    clocks (aggre-noc: 2, system-noc: 1), required where present and
    disallowed otherwise, matching the sdx75/glymur shape.
  - Made #power-domain-cells required on the Kuno GCC binding and
    declared it on the SoC gcc node, since the Kuno GCC hosts GDSCs and
    is a power-domain provider (following qcom,sdx75-gcc); the driver's
    GDSC support will follow separately.
  - Made the GPIO65/66 QDSS CTI trig1 funcsel-3 route selectable: added
    a distinct qdss_cti_trig1_mire pin function (and allowed it in the
    TLMM binding enum), as the duplicate funcsel-2/3 entry left
    funcsel-3 unreachable.

Changes in v2:
- Addressed v1 review feedback:
  - Reworked soc: qcom: geni-se commit message; dropped the Fixes: tag.
  - Reworded dt-bindings commit messages to the "Document X for the
    Qualcomm Kuno SoC" one-liner form.
  - Canonicalized copyright headers on interconnect binding / driver /
    NoC ID header to the single-line Qualcomm Technologies form.
  - Dropped unused <linux/mod_devicetable.h> from the interconnect
    driver.
  - Fixed MODULE_DESCRIPTION casing "KUNO" -> "Kuno" in the interconnect
    driver.
  - Extended interconnect binding to optionally allow up to four QoS AHB
    clocks (matches sdx75/glymur shape).
  - Cleaned up brace/space style in gcc-kuno.c to match peer clock
    drivers.
  - Reworked initial DTS: moved idle-states / domain-idle-states inside
    cpus{}, wrapped fixed clocks in a clocks{} container with peer node
    names (xo-board, sleep-clk), dropped the pcie_pipe_clk fixed-clock
    stub (the GCC 4th clock now uses <0> in DTS to match the sdx75
    idiom; the YAML example uses a named placeholder), dropped the
    RPMHPD_CX power-domain reference on GCC (Kuno GCC has no GDSCs /
    no corner votes / no pm_runtime, so the reference was inert), and
    added a bootloader hand-off comment on the memory node.
